DESCRIPTION
The DS10CP154A is a 1.5 Gbps 4x4 LVDS
crosspoint switch optimized for high-speed signal
routing and switching over FR-4 printed circuit board
backplanes and balanced cables. Fully differential
signal paths ensure exceptional signal integrity and
noise immunity. The non-blocking architecture allows
connections of any input to any output or outputs.
The switch configuration can be accomplished via
external pins or the System Management Bus
(SMBus) interface. In addition, the SMBus circuitry
enables the loss of signal (LOS) monitors that can
inform a system of the presence of an open inputs
condition (e.g. disconnected cable).
Wide input common mode range allows the switch to
accept signals with LVDS, CML and LVPECL levels;
the output levels are LVDS. A very small package
footprint requires a minimal space on the board while
the flow-through pinout allows easy board layout.
Each differential input and output is internally
terminated with a 100Ω resistor to lower return
losses, reduce component count and further minimize
board space.
